Penguins in Antarctica

Data

For this analysis, we will use the penguins data set from the palmerpenguins package. The website belonging to this package can be found here.

The data set contains size measurements, clutch observations, and blood isotope ratios for three penguins species observed on three islands in the Palmer Archipelago, Antarctica, over a study period of three years (Gorman, Williams, and Fraser 2014).

Figure 1 shows a scatter plot of the flipper length against the body mass of all penguins in the data set.

The data set comprises measurements of three types of penguins, namely:

• Adelie 🐧

• Chinstrap 🐧

• Gentoo 🐧
